CALVIN T. CUNNIUS, OF LONG BRANCH, NEW JERSEY Specification of Letters Patent.

Patented Oct. 27, 1908.

Application filed April 8, 1908. Serial No. 425,956.

To all whom it may concern:

Be it known that I, CALVIN T. CmvNIUs, a citizen of the United States, and a resident of Long Branch, in the county of Monmouth and State of New Jersey, have invented a new and Im roved Column, of which the following is 2'. Kill, clear, and exact description.

This invention is an improvement in columns, relating rimarily to columns built up of a plurality o staves,-nsually of wood and joined. together by a suitable number of hoops or bands.

Stavecolumns, especially for outside work, as now generally constructed are not lasting, for the reason that the joints betwecnthe staves soon break and the stave-s consequently spread apart, warp and twist. I aim to overcome this difliculty by constructing the column of a plurality of staves, all oi which are of approximately the same relative taper, wlth one stave'made of an inner and outer section substantially equal in length to the other stavcs.

staves I pass circumferentially of the column,

Through the a wire hoop or band, with the free ends of the wire emerging at the inner section of the sectional stave, Where they are suitably joined and operate to bind the staves together. The outer section of the sectional stave covers and obscures the inner section and the connections between the ends of the several hoops. A column thus constructed presents on the outside no joints, except along the lines the several staves abut.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate correspmiding parts in. all the views.

Figure 1 is a side elevation of a column complete constructed in accordance with my invention; Fig. 2 is a plan of the same; Fig. 3 is a fragn'lcntary olevational view of the column on an enlarged scale, with the outer section of the scctional stave removed; Fig. 4 is a section substantially on the line 4-4 of Fig. 3; and Fig. 5 is a fragmentary section similar to Fig. 1. on an enlarged scale.

In the construction of my improvcd colump 1 employ a suitable number of staves 5. all of which are of the same relative taper and prclerably have engaging tongues and groovcs (5 formed on their abutting edges. All of the staves are of the same construction except one, which is made in tvvo sections, an inner sect on 7 and an outer section b, the inner secti inner face, for engaging in groove COI'IGSPOIiCllHg to the tongue and groove of each of the other sections, and the outer section having longitudinal tongues 9 at opposite sides, preferably adjacent to its counterpart grooves in the contiguous stavcs.

Each stave is provided at suitable intervals with a transverse aperture, preferably in line with its tongue and groove,- which registers with lilreaperturcs in adjacent staves when the several staves of the column are placed together, and forms a passage for the reception of a band 10, preferably of wire, the free ends of the wire eincroinp in a slot 1.] at the inner section of the sectional stave, and being revorsely tln'eaded, as best shown in Fig. 4. ()n the threaded ends of each wire is screwed a turnbuclih-i 12 having atrans verse intermediate opening 13, through which it may be engaged in tightening the wire, this tighteningaction obviously operating to firmly bind theseveral staves of .the column together. The turnbuckles all fall. within the plane of the outer face of the inner section of the sectional stave in order that they will not interfere with the driving of the outer section of this stave, into place, which driving obviously is in the direction of the small end of the column, should the column be of tapering form. After the column has been assembled it is in readiness to beturned to the required form, which can be performed without fear of loosening the staves.

I am aware that prior to my invention, stave columns have been'in contemplation composed of a number of tapering staves, the tapering ends of which lie in the same direction; and one 01' more parallel staves, with a wire hoop passing through the several staves circumferentially of the column and binding the staves together, the ends of the wire where joined being covered by the outer section of one of the parallel staves, which outer section is made in two or more lengths. A column embodying this construction is disclosed in Letters Patent No. 840,639, granted to (i. W. lioggie, January 8, 1907.

l, lioucvor, believe it to be broadly new to c nstruct a column of a plurality of staves all of which are of approximately the sane taper, with a band passing through the s'cv era-l stavcs circuml'errntially of the column and binding the n togcther, one of the stavcs being made in two sections, on which line the end. of the bands are joinedtogether and are having the tongue and l'covered by the outer sgi2 .ti0I1-Qf the stave extending approximately the full length of the column. 'lhis construction not only embodies the desirable and eflicient method of connectingl the staves together, but permits of all of t e staves being made of the same relative ta er, producing a column, when completed, aving no transverse seams, which,

are objectionable in a finished column.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

7 1. A column composed of a lurality of staves having abutting edges of tlie same relative taper, each stave having a transverse a t e adjacent staves, a band passing through the a erture of the staves having its ends re verse y threaded, and a.turnbuckle engaging the threaded ends of the wire for drawing the staves together.

2. A column com osed of a plurality of staves ofthe same re ative taper, with one of said staves consisting of an inner-and outer section, the outer section being unbroken and approximately equal in length to the other staves of the column, and a band passingthrough the several staves circumferentially of the column, with the free ends of the band joined together at the inner section of the sectional stave.

1perture registering with a like aperture in- 3.A column composed of a plurality of staves of the same relative taper, said staves having engaging tongues and grooves on their abutting'edges, and a band passing through the several staves circumferentially of the column on a line intersecting the tongues and grooves, operating to bind. the staves together.

4. A column comprising a plurality of staves, an inner stave section having a slot, 9. wire band passing through the several staves, with its free ends reversely threaded and passing into said slot, a turnbuckle in said slot in threaded engagement with the threaded ends of the band, and an outer stave section covering the inner stave section and the turnbuckle.

5. A column composed of a plurality of abutting staves, a band passing through the several staves circumferentially of the 001- I
